I bought the cheapest blades I could find, no air foil, works just fine.

That's what I always have done, but when I tried that on the Sportage, the driver's side wiper skipped at road speed. The airfoil wouldn't attach to it so I had to find something else. You're lucky if you can get by with the regular blades on your Sportage. But hey, now it looks like you can find deals on the beam blades for almost the same price as the regulars. You should try a set if you can find a deal - it's worth it.

Oddly enough, I used to buy the blade style wipers for other vehicles. I needed some new wipers one day, figured I would try what you did and that was attach the airfoil to the new ones, no dice. I gave up and said screw it, forgot about it (since I walk to work, my car sits in the garage all the time). Went to drive up to see family, never having swapped the old ones back on and BAM, everything worked fine at highway speeds. No skipping or chattering. Besides, odds are that if the wipers are in use, I am going a little slower than normal anyway. But hey, whatever works.
